Abstract

The utility model provides an LED (light emitting diode) lamp enclosure. The LED lamp enclosure is a bell jar-shaped structural part and comprises a thin-shell metal insert and a heat conduction plastic part wrapping the metal insert, wherein the thickness of the heat conduction plastic part between the metal insert and the outside air is less than or equal to 2mm. The metal insert is of a Z-shaped structure; the lower part is provided with an inner plane for mounting an aluminum plate; and a mounting slot for mounting a lampshade is formed between the inner plane after mounting an aluminum plate and the aluminum plate. Through the LED lamp enclosure provided by the utility model, the safety and radiating effect of the LED lamp are improved, and the cost of the LED lamp is reduced.

Description

The LED lamp housing

Technical field

The utility model relates to light fixture, particularly a kind of LED lamp housing.

Background technology

The heating problem of LED wick sheet badly influences the light efficiency of led chip.In order to solve heating problem, the heat that must effectively LED wick sheet be produced is distributed in the external environment.Therefore the shell of LED lamp must have heat sinking function.Generally adopt metal to make the LED lamp housing on the market, radiating effect can improve like this, but owing to metal conducts electricity; Therefore; Must do insulation to the power unit of LED lamp and handle, nonetheless, the cost of security and lamp housing remains the two large problems that the LED lamp must solve.

The utility model content

The purpose of the utility model just is to overcome the deficiency of above-mentioned prior art, and a kind of safe, LED lamp housing that thermal diffusivity is good is provided.

For realizing above-mentioned purpose; The utility model adopts following design: a kind of LED lamp housing; Be the bell shape structural member, comprise shell shape metal insert and the heat conduction plastic parts that is coated on the metal insert outside, the thickness≤2mm of the heat conduction plastic parts between metal insert and the outside air.

Described metal insert adopts the Z font structure, and its underpart is provided with the inner plane that is used to install aluminium base, and forms a mounting groove that is used to install lampshade after aluminium base is installed and between the aluminium base.

Lower corners at the LED lamp housing is organized radiating ribs along circumferentially evenly being provided with more, and every group of radiating ribs formed sandwich by two radiating ribs, on the transverse plane between each group radiating ribs, is respectively equipped with a plurality of graininess convexities.

The thickness of described radiating ribs is 1.8-2.2mm.

The beneficial effect of the utility model is:

1. improved the security of LED lamp: it is the insulating heat-conductive product that general new material Science and Technology Ltd. is set in Shanghai that there are heat conduction plastic parts, plastics in metal insert outside, and resistance to compression can reach more than the 6000V, and meets the V0 flame retardant rating, and security is better.When LED lamp user held shell, security was secure.

2. improved the radiating effect of LED lamp: the metal that the diffusion of heat mainly relies on high conductance spreads on a large scale, and in order to improve the diffuser efficiency from the metal to the outer surface, product has been taked the thin-walled property design.

3. reduced the cost of LED lamp: the metal insert of the utility model use is non-appearance component, therefore only needs simple processing to get final product, and the more traditional LED lamp housing of cost has significantly reduction.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.

Referring to Fig. 1; Cooperation is referring to Fig. 2, Fig. 3, Fig. 4, and the LED lamp housing of the utility model is the bell shape structural member; Comprise shell shape metal insert 1 and the heat conduction plastic parts 2 that is coated on the metal insert outside, the thickness≤2mm of the heat conduction plastic parts between metal insert 1 and the outside air.

Metal insert 1 adopts the Z font structure, and its underpart is provided with the inner plane 11 that is used to install aluminium base 3, and mounting groove 12 that is used to install lampshade of formation between aluminium base 3 backs and the aluminium base is being installed.

Lower corners at the LED lamp housing is organized radiating ribs 4 along circumferentially evenly being provided with more, and every group of radiating ribs formed sandwich by two radiating ribs, on the transverse plane between each group radiating ribs, is respectively equipped with a plurality of graininess protruding 5.The thickness of radiating ribs is 1.8-2.2mm.

The utility model adopts the processes of embedded injection moulding, and to guarantee combining closely of plastic cement part and metal insert, wherein metal insert partly has the screw hole design.LED lamp source/aluminium base can be fixed on the lower surface of metal insert through self-tapping screw, and the screw thread design is adopted on the plastic parts of heat conduction simultaneously top, so that screw thread lamp angle to be installed.The heat conduction plastic parts uses the heat conduction engineering plastics.This project plastics are the insulating heat-conductive product that general new material Science and Technology Ltd. is set in Shanghai, and resistance to compression can reach more than the 6000V, and meets the V0 flame retardant rating, and security is better.
